The tricky task is to distinguish between those 3 cases—and to find general rules which can do this in every situation in a unique way, and represent your concept of morality at the same time.
Well, yes, finding a simple description of morality is hard. But you seem to be asking if there’s a possibility that it’s in principle impossible to distinguish between these 3 cases for some situation—and this is what you call a “true moral dilemma”—and I don’t see how the idea of that is coherent.
Most dilemmas are situations where similar-looking moral guidelines lead to different decisions, or situations where common moral rules are inconsistent or not well-defined. In those cases, it is hard to decide whether the moral system prefers one action or the other, or does not care.

I did not call anything “true moral dilemma”.
